Thinking of starting up again, but have some ??'s

I have had about 4 fina/test cycles. My last one was about a yr ago. My concern is that during my last cycle I would do my injections and in the delts and glutes I would get pressure/force when injecting. Sometimes the needle would start to rise up and the pressure would be so strong that I could barely get the oil in. I was wondering if this was from scar tissue? And does your body ever repair itself? I was using 25g and 27g pins mainly 27g. Thanks

I would say rotate to some other sites and don't use 27g pins for oil. 25g should be the highest you go unless it's water based or slin ect....
